Now that `apps/oxlint` and `napi/parser` are both ESM packages (#13723 and #14042), we can use `.js` file extensions for all ESM files, rather than the mix of `.js` and `.mjs` file we had previously.
It's less confusing having to remember what's `.js` and what's `.mjs`, and avoids ugly workarounds like #14038 (`.d.mts`??).
Completion of the work begun in #13432. Make `oxc-parser` package fully ESM.
Aside from adding `"type": "module"` to `package.json`, only other change required is renaming `webcontainer-fallback.js` -> `webcontainer-fallback.cjs`. All other files already have the extension matching their ESM/CommonJS content.
Add visitor keys export to `oxc-parser` NPM package. This is useful in itself, but also the first step towards an ESTree walker.
Visitor keys are based on `@typescript-eslint/visitor-keys`.
It'd be ideal to generate visitor keys direct from Oxc's own types, but that's proving difficult due to all the custom serializers we use to translate to ESTree. So using the shortcut of borrowing from TS-ESLint for now.
Oxc's AST is slightly different from TS-ESTree (notably Oxc's AST adds `ParenthesizedExpression`). But apart from those few differences, TS-ESLint's AST and Oxc's are identical, and I made a PR to TS-ESLint earlier this year (https://github.com/typescript-eslint/typescript-eslint/pull/11279) to ensure visitor key order is correct, and matches Oxc.
To avoid adding a runtime dependency on `@typescript-eslint/visitor-keys`, extract the data from TS-ESLint in `oxc_ast_tools`, amend for Oxc/TS-ESTree differences, and re-output it as a simple object literal.
This approach will be faster at runtime, as the object's shape is consistent, and also avoids a dependency.
Duplicate of #9555, but just stacked on top of #9566.
`napi-rs` for some reason omits the `export * from '@oxc-project/types';` line from `index.d.ts` when building for WASM.
I don't know how to fix that, so added a hacky script to fix up `index.d.ts` manually. This is not at all ideal, but at least it now compiles and CI passes.
